MANGLE on IRONING MACHINE.

Appneation filed september 25, 1920. serial mi. 412,825.

To all whom it may cmtcem:

Be it known that I, FREDERICK W. Vonoz,

a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State of 6 Illinois, have invented a Mangle or Ironing i ication.

This invention relates to improvements in mangles, or ironing machines, and has for 10 its principal object to provide an improved construction of machines of the class described. Other objects and features of my invention will appear-as the description proceeds.

The invention-consists in the construction, combination, and arrangement of parts, as are described in the following specification, in connection with the accompanying drawings, and more specifically pointed out in the appended claims.

In the drawings, Fig. 1 is a side` view of a machine embodying my invention, with the heating element in one position.

Fig. 2 is a front view of the machine, with the heating element in the positionV shown in Fig. 1.

Fg. 3 is a side view, with the heating element ina second position.

In 'the embodiment of my invention illustrated herewith, a frame A, comprises side supporting members 10, 10, a pair of longitudinally disposedcross members 11,11, spaced apart andadjacent the top ofsaid side members, and other suitably disposed cross members 12. The cross members 11, 11, and 12, preferably comprise tubular bars or rods, mount d in suitable brackets 11b, 11"

Machine, of whichthe following is a speciattached to si e supports 10, 10. The frame' v. is mounted on casters l13, 13, each having a 40 mounted on the frame, and provided with a 'ball bearing 13 interposed between the upl perend of said shank and a cap screw 13, threaded in the upper end of said sleeve and adapted to be readily adjusted so as to regulate the height of the caster when the machine is used on uneven oor surfaces.

An ironing roller 14` is mounted'fabove and longitudinally of the frame A, and is supported at one end by a bearing bracket 15, and at the other end by a worm gear housing 16, the two last mentioned members both being mounted on the cross members 11, 11a, .by means of sleeves 17,17, and 18, 18, al'-v shank 13 mounted to turn in a sleeve 13by ranged to be movably adjusted therealong, in order to provide easy assembly and disassembly of the roller,and to permit the use of rollers of varying lengths, as desired.

The bearing vbracket 15 is preferably provided with a hollow end .portion 15, suitable for containing grease or other lubricant,

packing gland 15, suitably secured to the for the roller shaft 15d. rlhe bearing con-v and having annular ball bearings 15b of any approved pattern, retained in place by a.

struction for the opposite end ofthe roller i' 'is similarly designed, and comprises roller bearing 16, and packing gland 16b mounted on the housing 16, aboutthe shaft 16. A

worm gear 16d is also carried on the said shaft 16c within the said housing, the latter .being split on a horizontal plane, as shown in Fig. 1, to afford access to the mechanism therein. Y

A work table20 is provided on the front, or advance side of the machine, and comprises a horizontal board 21, having its inner margin adjacent the roller 14,l and supported by forked brackets 22, 22, which rest onthe front cross bar 11, .and hinged links 23, 23,

which connect the outer marginof the table to the frame. This arrangement allows the table to be folded downwardly, for compact- .ness in shipping, When desired.

A folding hopper 24 is also hin ed to the, front of the frame, and supporte b ylinks 25, 25, attachedto links'23, 23. The lopper is adapted for holding the Awork beforeit `is placed in the man le. l

A receiving tab e 26 is provided at the sol rear of the machine, and may be constructed l similarly to the front table 20, excepting that it is preferably arranged somewhat lower, as shown. In addition, the receiving table is arranged so that it may be swung. to a second` position, shown in dotted lines in Fig. 1, in which the vsupportin 27,27, are swungv abouty the pivots 2 a,'27,

, and theforked brackets 28, 28,"engage with 'a crossmember 28, tohold Athe table in substantially horizontalA position, as shown. The purpose of this arrangement is to allow a larger drop for pieces Oflarge dimeni sions as they are passed thru the machine, thereby facilitating the ironing and foldin ofpieces such as sheets and the like. f

plurality of fingers29, 29 are arranged links AEnd-plates 34 and 35 are ,above the roller 14, and having a curved heating-plate 31, or hot plate conforming substantially with the shape of the roller.

The element may be heated by any suityable means, such as gas, or electricity, but'y in the embodiment illustrated, I have shownl a gas-heated device, comprising a hood 32, and a as burner 33 of an approved pattern, extending the length of the hot plate 31. provided at the respective ends of the heating element, onA

which the burner 33 is supported. A pair 'of laterally extending brackets 34a and 35 are connected with the end platesv 34 and 35,

respectively, and connect with'vertically disposed supporting arms 36 and 37 respectively. The heating element is preferablyA mounted on said arms by means of resilient i connections 38, 38, each comprising a casting` 38a attached -to the upper end of said arms, and having a vertically dispesedrpin 38b extending through each of the brackets 34 and 351- and connected thereto by a spring 40 mounted on thev upper end of said pin 38b and connected with an adjustable 4win nut 39, to regulate the tension of the y heatlng elementupon the roller.

The gas burner 33 is fed by a suitable pipe l41, preferably supported by the adjacent casting 38a and having a valve 42 of any suitable type, adapted to-be controlled by a lever 43, as will be more fully described. The lower ends 44, 44 of the v'suppt'nting arms 36, 37, are connected together by a cross member 45. A pair of suitable lugs 46, 46, are carried by said arms and move in vertically disposed'guides 47 47, attachedk to the s1de members 10, 10, as shown. A pair of rocking links 48, 48 are also connected to said arms, and pivoted to the frame, preferably on the rear cross-bar 11" thereof. The arrangement is such that the heatino element 30, supporting arms 36 and 37, an cross-bar 45 arelmovable as a unit, which movement is controlled by the links 48, 48, and guides 47, 47, so as to displace the heating element 30 rearwardly with respect to the roller 14 as it is raised therefrom, in the position `shown .in Fig. 3. The purpose of this arrangement is to provide an unobstructed u per surface of the roller so that work may be placed thereon in posi- .tion for beginning the ironing operation.

Themechanism for actuating thew heatin element and lassociated parts just describecomprises a foot-lever or treadle 49, pivoted on the cross-bar 45, and having an upwardly y 4toggle device, which in the constructionk illustrated is the bar 11, as above described. The toggle device is also provided with a suitable stop, as for instance an odset portion 53 of the toggle joint 53a, which limits the relative movement of the levers to form a` locked relationv thereof, when they are moved slightly beyond alignment with each other, and the heating element is in engagement with the roller, as illustrated in Figs. 1 and 2. The toggle is unlocked, or 5 broken by means Vof a second arm 51a preferablymade integral with the lever 50, and extending forwardly from the machine in. position to Vbe manipulated by the operator.

Mechanism for actuating the roller 14 comprises a worm (not shown) meshed with thev worm gear 16d in the gear housing 16,

vas already described, and driven by a suitable electric motor 54 mounted on the frame.

Electrical connections Vfor the motor comprise a socket plug 55, including .a switch of the usual type operated by a pull cord 56.

Said pull cord is attached to a rocking armv 57 4pivotally connected to the frame, and adapted to be actuated by a cam 58 mounted on the arm 37 By means of the arrangement just described, the motor is automatically started by opening the supply circuit to the driving motor when the heating element is brought into contact with-the roller, and immediately stopped again as the heating element is withdrawn.' The switch 55 may also be independently actuated by the operator, by vmeans of the control rod 55a, attached to the arm 57.

Anr automatic control for the heating device comprises the valve 42 for controlling the gas supply to the hot plate, and a con-i into o erating position on the roller, and

diminished when the heating element is raised. A preferred device for controlling the said valve comprises a V-shaped slot in the lever 43, which will allow the valve 42 to be manually opened when the heating element 30-is inrthe raised position shown in Fig. 3, and itis desired to heat the hot plate l 3l-preparatory to use, but which will automaticallycontrol the valve so as to open it when the hot plate r`is brought into contact with the roller, and close it when the hot plate is raised. l

The use and operation of my invention is as follows:

The heating element is normally held in its raised position by thev tension device 52, as illustrated in Fig. 3, in which it is 20 the treadle downwardly to lower the heating element -into position shown in Fig. 1, in which case the valve 42 will automatically be opened, as shown. When the hot plate has been heated to the desired degree, the mechanism is then moved to the position shown in Fig. 3, and the machine is now ready for-operation. The work is placed along the roller 14, and the treadle 49 is depressed by the operator, bringing the hot plate into contact with the work and simultaneously starting rotation of the roller by turning on the current to the driving motor 54 at switch plug 55 by means of the cam device 57 before described'. The roller thus starts to revolve, and the work is carried under the hot plate and deposited on the receiving table 26. It will be noted, that the toggle levers 49*l and 51 become locked when the heating element is brought into contact with the roller, so that after the treadle 49 is once depressed, the pressure may be removed therefrom, and the ironing operation may continue until it is again desired to lift the heating element. This is accomplished by depressing the lever 51,

which unlocks, or breaks the toggle, and allowsthe heatingelement to be raised by the spring 52.. As the heating element is raised, the driving motor and roller are stopped by action of the cam 58 and switch 55, and similarly, the gas supply is di'- minished by movement of the lever 43, which partially closes the valve 42 to such a degree that the hot plate will not be heated to a dangerous degree. iii case the machine is not used for a relatively short time, yet will be sufiiciently lheated for subsequent use, as desired.

In the event that relatively large pieces,

such as sheets lor the like, are to` be ironed,

the receiving table may be moved to a lower position, so as to facilitate the handling vof such work, as already suggested.'

Among novel features of construction not already pointed out, .is the means whereby the power is applied approximately at the center of the'cross-rod 45 'associated with the heating lelement 30. This constructionaffords an equalization of pressure ofl the heating element on vwork of uneven thicknesses when applied to opposite ends 'of theroller.

It ,will be understood that I have shown and described simply one form of my invention, and in doing so, have set forth certain parts and relations thereof, but I wish it to be understood that I do not thereby desire to limit myself to these particular forms nor to this particular embodiment of my invention, excepting as specifically limited in the following claims:
